MACHINE FOR MOUNTING SHOES ON LASTS.

Specification of Letters Patent. Patented Oct. 14, 1919,

Application filed December 14, 1917. Serial No. 207,101.

Be it known that I, Nonwooo H. KNOWL- 'lON, a citizen of the United States, residing at Rockport, in the county of Essex and State of Massachusetts, have invented certain Improvements in Machines for Mounting Shoes on Lasts, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for use in the manufacture of shoes for mounting shoes on lasts. Such machines are of particular utility in the manufacture of turn shoes for the purpose of mounting the shoe on the second last after the shoe has been turned, but it will be evident from a 0011- sideration of the construction and the manner of operation of the machine herein shown that the invention is not necessarily limited to use with this particular type of shoe.

An important feature of the invention consists in novel means for utilizing a series of repeated impulses for effecting relative movement of a shoe and a last to mount the shoe on the last. An advantage in the use of such means, as distinguished from means for performing the relasting operation by one continuous relative movement of the shoe and the last, is that there is less danger of damaging or of' unduly straining the parts of the shoe. The machine herein shown is provided with power operated.

means, including a continuously driven member, for imparting the series of impulses to the work, and the illustrated organization enables the operator eifectively to control the application and the force and incidentally, the amplitude, of such impulses, thus permitting the operation of mounting the shoe on the last to be performed in an expeditious manner with comparatively little eifort on the operators part.

Other features of the invention reside in' a novel construction and arrangement of shoe engaging means and last engaging means relatively movable to cause a lastto be forced into a shoe, in novel means for gripping a shoe, novel means affording provision for relative lateral adjustment of the shoe and the last, and in various details of construction and combinations of parts, all

of which will now be described with reference to the accompanying drawings and will be pointed out in the claims.

In the drawings,

' Figure 1 is a view in side elevation of a machine in'which the invention is embodied, portions of the structure being shown in vertical section,

Fig. 2 is a view on a smaller scale than Fig. 1, showing the machine in front elevation; and

' Fig. 3 is a sectional view on the line 33 of Fig. 2.

The machine herein shown is provided with means for engaging and gripping or clamping the forepart of a shoe in which a last has been partially inserted, this means being mounted upon a substantially horizontal lever 2 which is pivoted at lto an upwardly extending arm 6 on the frame or standard 8 of the machine. Pivoted at 10 on the: front endofthe lever 2-isa clamp support 12 having a guideway extending lengthwise thereof in which is mounted a slide 14 which carries a pad 16 shaped for engagement with the bottom of the sole of the shoe. The slide 14 is freely movable up and down in the guideway and when the machine is idle is supported upon a'pin 17 at the lower end of the guideway. Mounted on pivots 18 -,on the slide Mare arms 20 which carry pads 22 shaped for engagement with portions of the shoe at the sides and over the top of the forepart, as shown in Fig. The pads 16 and 22 are preferably of rubber or similar material such as to permit the shoe to be firmly gripped and held without injury either 'to the sole or to the upper. Mounted on pivots 2 1 on the sup port 12 are arms 26 which carryrolls 28 positioned for engagement with the outer sides of the shoe gripping arms 20, the outer sides of these arms extending indivergent relation, asshown in Fig. 2. A spring 30' connected to the arms 26 tends to pull these arms toward each other, the inward movement of the arms being limited, when no shoe is in the machine, by engagement of lugs 32 on the arms with the sides of the support 12. When the parts are thus positioned the slide 14: is at its lower limit of movement, in engagement with the pin 17 ,v and by reason of the position of the clamp arms 20 relatively to the operating arms 26, the latter are ineffective to force the clamp arms inwardly; A comparatively light spring 3i connected to pins on the arms 20 tends to spread these armsand to hold them continuously in engagement with the rolls 28, and when the parts are in their idle positions, as above described, the clamp arms are thus opened for the reception of a shoe.

After the forepart of a shoe has been insorted between the clamp arms 20 with its sole in engagement with the pad 16, the clamp arms are caused to close upon the shoe :by relative movement of the support 12 and the slide 14 effected as hereinafter described, this relative movement causing the clamp arms to be wed-god between the rolls 28 on the arms 26 against the tension of the spring 30. It will be evident by reference to Fig. 3 that the pads 22 are so constructed .as to press not only laterally against the shoe "but also in the direction of the shoe bottom, thus holding the shoe in firm engagement with the sole supporting pad 16. A comparatively light spring 36 tends to swing the holder 12 backwardly into engagement with a stop lug 38 on the lever 2, while permitting the holder to be swung torwa-r-dly into a position convenient for the reception of a shoe and also per-- mitting it to swing relatively to the lever during the operation upon the shoe and the last.

The machine is also provided with last engaging means, which, in the construction shown, comprises a member 44 shaped to out brace the heel end of the last and mounted upon a lever 40 which is pivoted at on the arm 6.. Below the front end of the lever 10 is operating means for imparting to the lever .a series of upwardly directed impulses. This means comprises a cam 46 fast on a shaft v48 which is driven by means of a belt 50 from a driving shaft .52. A spring plunger .54; which engages under the lever 40 tends to support the lever above the path of movement of the cam 46 while permitting it to be moved by downward pressure of a last into position to he operated by the cam. The lever 2., which carries the shoe enging means, is connected by means of a rod 55 to a treadle 56 whereby the lever may be moved downwardly against the tension of a spring 58. By the operation-oat the t-rea-dile 56 the shoe and the last are thus moved downwardly to cause the last to engage the memb r 4 1 and to force the lever -(:l .-11 wardly into position to be operated by the cam 46.

In the operation of the par-ts above described the holder 12 is swung forwardly and a shoe in which a last has loeen partially inserted by hand is positioned between the gripping pads 16 and 22 with its sole resting on the pad 16. The support 12 is then swung rearwardly with the shoe and the last to position the heel end of the last over l'h member 4.4, and the treadle 56 is depressed.

The heel end of the last is thus moved into engagement with the support H and by continned depression of the treadle the support 12 is moved relatively to the slide ll, causing the arms 26, by engagement oi their rolls 28 with the outer sides of the clamp members 20, to force these members firmly against the sides and top of the shoe, thus clamping the shoe between the two pads 22 as Well as between these pads and the bottom engaging pad 16. By the same movement of the lever 2 the lever l0 is forced downward against the spring plunger 54 into the path 01 movement of the rapidly rotating cam 46. The cam then imparts a series of rapidly repeated upwardly directed impulses to the lever 40 and the membe' H against the heel end of the last, thus imparting to the last a series of impulses in the direction of the toe end of the shoe and forcing the last foiwardly into the shoe in successive steps. Moreover, the operative may so regulate hi pressure on the treadlc 56 that the contact of lever l-O and cam -16 will be discontinuous, in etl ect a series of impacts, with the result that the last will receive a series of rapid but separate and distinct blows, instead of a more or less continuus series of impulses. It will be evi dent that downward pressure upon the treadle 56 also renders the shoe engaging means effective with a tendency to force the shoe over the last, and that the shoe engaging means and the last engaging means are thus mutually cooperative in their operations upon the ditlcrent respective portions of the work to cause the last to be forced into the shoe. t will also be evident that increase of pressure upon the treadle 56 notonly renders the shoe engaging means increasingly effective to force the shoe over the last, but also, by i'novinp; the lever 40 farther into the path of ll'lOVGll'lQllt of the cam 4E6, increases the leverage of said cam against lever 10 and causes the force of the impulses imparted by the cam to the lever,

as well as the extent or amplitude of the oscillatory movenient of the lever, to be in creased. The downward pressure of the lever 2, moreover, tends to move the support 12 relatively to the clamp holder slide 14 and thus tospread the arms 26 farther apart against the tension of the spring 30. cansing the shoe to be held more firmly in proportion to the increase in ellectiveness of the means for moving the shoe and the last relatively.

After the last has been firml; seated in the tonepart of the shoe by 'the cooperative action of the cam and the t-readle. pressure upon the treadle is released, rei'idering the .1 ring 58 effective to raise the work from the its removal from the machine. After the removal of the work the heel portion of the last support into a position to permit shoe will be drawn over the last, preferably with the aid of some tool such as a shoe hOrIL I v v w a In the'construction shown the member lhwhich embraces the heel end of the last, is mounted on the lever 40 with freedom for sliding movement transversely of; the lever within limits determined by stop screws 45. This construction permits the last to'be differently angled with reference to the shoe support for difi'erent' shoes, such as rights and lefts, and also permits the operator to adjust the last laterally with reference to the shoe during the operation of the machine in such manneras to insure that the last shall be directed accurately toward the toe and of the shoe without undue drag upon either side of the shoe such as would tend to distort the shoe as'well as to retard the operation of the machine. It will be evident, moreover, that this construe tion permits last engaging'member's of different shapes" to besubstituted' readily, if desired, for-difierent styles of lasts.
